Well, you could rename the original reviews module to reviews1 and keep the original one too. You also would need to go through all the files in the reviews1 module and change any references from reviews to reviews1

Then you also need another reviews table in your database.
example
nuke_reviews
nuke_reviews1
You should be able to copy the info for the reviews table and rename it as reviews1 then upload it to your database.
ALSO..lol You would need to change the SQL queries in the reviews1 module to point to the review1 table instead of the original reviews table

confused yet?
